    Picked up a CMMG .22 conversion.

    It's in my M4 with the Gemtech G5 can and shooting Remington subsonic .22. The kind that comes in the same box as the Thunderbolts but say Subsonic instead. It doesn't cycle for shit but the CMMG packaging even says it doesn't recommend Remington plus it's subsonic. It's sooo quite though. Hard to tell from the video but the sound of a dry fire or FTF is about as loud when the hammer falls.

    PS, don't mind the mess and no I'm not worried about lead build up in my can.

    Yes, I'm firing into the backyard. I know its not a brilliant idea but I wanted to check it out. Not something I do on the regular. I called gemtech and they told me it would take 60k + rounds to start causing sound reduction. I just wanted to try it out.

    I know I'm taking a risk though. With how quite supersonic is, I'll probably end up getting a dedicated upper as well. I just really wanted to see how quite it would be through the can. and I was shooting at about 20 yards and was really impressed with the groupings considering the twist rate is so high.

    Go document zero shift on the G5 with .223/5.56, I would be interested in the results.

    I thought about running .22 through my AAC can for shits and giggles, but figured why bother.

    You'd be surprised how fast .22 can build up inside a can. Since the G5 is SS, Ti, and Inconel, it's safe to give it the 50/50 bath of hydrogen peroxide and white vinegar. it makes lead acetate which is pretty nasty and needs to be disposed of at a hazmat station but it removes all lead buildup.

    The magazine that came with my kit had some issues cycling any kind of ammo reliably...the conversion itself was solid though. I ended up selling it and plan on building a dedicated .22 gun since I still have this free Noveske lower sitting around doing nothing.

    You'd be better off buying it from AIM as DrewDown's was the last CMMG kit I plan to sell for the time being. AIM is unloading the kits at damn-near cost.

    I'm pretty sure that's bullshit. What you can do is use "the dip" (50-50 mix of hydrogen peroxide and vinegar) but only if your can is not made of aluminum.

    And if you do use the dip do it outside, it emits toxic fumes.

    Agreed. Cleaning .22 buildup in any part of a firearm/suppressor is not going to be cleared up by shooting .223 through it again.

    I wear a mask when doing the dip. You can solidify lead acetate by adding table salt (college chemistry was useful after all.) It makes it a little easier to take care of than a liquid.

    The problem with .22 is that it's filthy and leaves tons of lead behind on the supressor baffles. Lead buildup on .22 cans is the reason for so many companies coming out with take apart .22 cans. A sealed .22 can will double in weight in as little as 10,000 rounds due to the lead build up.. And at some point the lead buildup is so great that the sound reduction begins to decrease as well.
